For as long as reefs have existed they have been shaped by cyclones and intense storms. Almost every one of us have heard and most of you have seen the Coral reefs but did you know what actually these are: HHS Vulnerability Disclosure, Help Coral and macroalgal cover were negatively correlated at all island groups, and particularly when macroalgal cover was above 20%. Spatially extensive genetic surveys allowed us to infer signatures of asymmetric Many reefs are located in the cyclone zone due to the necessary conditions they require to grow. Scientists are working to find ways to protect it. In such cases, the affected coral ecosystems may not be able to recover fully from the disturbance, because critical parts of the ecosystem would no longer be present.
